Hello -
I have tried and tried to get my MCP and EFIS working with P3D v4 and PMDG737 to no avail. Ive downloaded the beta VAinterface and read/tried every post out there regarding loading order, admin rights, firewalls and virus sw. I'm getting a green icon when I load vainterface up and sometimes the MCP digits light up. A few times the course selector and nothing else worked. Most of the time nothing on the MCP works. Running Win10, 64 bit.
